The disease in which someone becomes a complete and utter ass, annoying anybody in the immediate area.
Ass- "Hey guys, you guys suck..and, I need to get new friends....and I hate you guys.

Other Guy- "Jesus Christ, hes come down with Richieitis. Come on, the only cure is bludgeoning the victim with golf clubs. *Beats Ass with clubs"

Ass- *sob* "I love you guys..."
